T0 all wtom t may concern:

Be it known that I, DAvID B. MORRISON, a citizen of the United States, residingat Kansas Oity, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Filters; and I do declare the following to be a full, clear, and exact description o f the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference markedl thereon, which form a part of this specification.

This invention has relation to improvements in filters; and it consists in the novel construction and arrangement ot its parts, as hereinafter described.

The object of the invention isA to construct a filter which can be placed in any cooler Without altering the construction of the cooler and which can be easily cleaned and removed from the cooler when desired.

The further object of the invention is to provide a filter which will be protected and not easily broken and which will be simple in construction and cheap in manufacture.

In the accompanying drawings, Figure l is a sectional view of a cooler with my improved iilter placed therein. Fig. 2 is a sectional view of the cooler, showing a modified form of the filter. Fig. 3 is a sectional view of the cooler,showin g another modification; and Fig. 4t is a sectional view of the lower portion of the cooler, showing still another vmodified form oi' the filter. e t A The cooler A is provided with the usual top A and the handles A2. RestingV on the bottom of the cooler is the lter-frame B,

which is supported by means of the legs B. The open frame B, as shown in Figs. l and 2, has slanting sides and a tlathorizontal portion C. The horizontalk portion C is also shown in Fig. et. The horizontal portion O is provided with an annulargroove in which is located a gasket O. Said gasket is adapted to bear against the innerwalls of the cooler and maintain a water-tight joint. The iilterframe B supports and holds in position the filtering-wall D, which consists of a ring open at the top and bottom, of any suitable filtering material-such as stone composition, (te. The screenE is adapted to rest on top of the with a cock I.

other suitable material.

filter-framel B, the said screen preventing the ice and other articles from reaching the filtering material and therebyprotecting the same. The bottom of the iiltering-frame B, as shown in Figs. l, 2, and 3, is conveXed, as at F, and resting on the conve/nity lF is a panV G,which is provided with a suitable handle G. The cock H connectswith the interior of the cooler. The pipe I leads from the exterior of" the cooler into the interior of the filtering-wall, and theouter end of Vsaid pipe I isprovided In the form ot the device as shownin Fig. 4 the receptacle L is adaptedto contain the ice, said receptacle beingmade of `vvire-n'ettin g or The said receptacle is adapted to slip between the walls of the iill tering material, and the said receptacle is retained in proper position within the filtering material by means of the bottom L', which comes in contact with the inner faces of the filtering material andthe frictional contact between the edges of the bottom L', and the inner face of4 the tilteringmaterial prevents the ice from `iioating the receptacle L out. Thus the water in the lower part of the cooler will be kept cool. In order to equalize the air-pressures above and below the horizontal portion O, the lower end ot the pipe M passes through the said portion O, the upper end of said pipe extending up and terminating in the vicinity of the upper end of the cooler. Furthermore, by means of the said pipe M the cold air from theupper portion ofthe cooler may enter the portion of the cooler below the hori- Zontal portion O, and thusvvater in the bottom of the-cooler'is refrigerated.

In operation water is poured into the cooler, which passes through the filtering material- D into the chamberK in a filteredcondition, and it is then drawn off when desired through the cock H. Any sediment which .does not pass through the filtering-wall will fall into the pan G, `which can be removed ,byfmeans of the handleG when it isdesired to clean the filter. Any Water or dirt which may have been deposited on the bottom of the filterframe F can pass through the pipe I by simply tilting the cooler and opening the cock I.

,In Fig. 2 an additional filter-plate D is provided, Which forms a coverfor the filter- By this construction the Water ing-ring D.

IOO

is first filtered through the plate D before passing through the filtering-ring D. This filtering-plate D can be made removable in order to remove the pan G.

In Fig. 3 the filter-frame B is provided With vertical Walls and the filtering-Walls D?. In this modification I provide the pan G With brushes G2 on the outer surface, so that when the pan is revolved by means of the handle G the brushes will bear against the Vertical Walls of the filter D and clean the same.

By the construction which has just been described it Will be noticed that the filterframe carrying the filtering-Walls and screen E can be placed in any cooler Without altering the construction thereof, and a filter is thus obtained with but little expense.

When it is desired to remove the filteringframe, the pipe I is disconnected from the lter-frame, and thus the frame is free to be lifted out.

In the form of the invention as shown in Fig. 4E to clean the perpendicular Walls of the ring D the receptacle L is lifted out and the edges of the bottom L', scraping against the inner faces of the ring D, scrapes off the dirt, Lito.

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is

1. The combination With a cooler of a filterframe supported on the bottom of the cooler, the top portion of the frame forming awatertight joint With the side of the cooler, a filtering-Wall supported by the filter-frame and the removable pan supported by the filterframe and located adjacent the lower portion of the filter-Wall.

2. The combination with a cooler of a filterframe resting onthe bottom of the cooler having its upper portion forming a Water-tight joint with the sides of the cooler, a filtering- Wall supported by the filter-frame, a convexed bottom for the filter-frame, aremovable pan resting on the bottom and a drain-pipe leading through the various Walls to the outside of the cooler.

3. The combination With a cooler of a filterframe resting on the bottom of the cooler having its upper edge forming a Water-'tight joint with the sides of the cooler, a filtering-Wall supported by the filtering-frame, a removable pan resting on the bottom of the filter-frame and a brush on the outside of the pan bearing against the filter-Wall and adapted to clean the same when the pan is removed.

4. The combination with a cooler of a filter- .frame resting on the bottom of the cooler havsupported by the filter-frame, an air-pipe passing at its lower end through the filterframe, and opening into the compartments above and below the filter-frame.

In testimony whereof I affix my signature i in presence of two Witnesses.
